📌 What is HTMX?

HTMX is an innovative library that simplifies creating dynamic web applications by leveraging:

  • AJAX
  • WebSocket
  • Server-Sent Events (SSE)

— all while maintaining a declarative approach.

Unlike traditional AJAX that often requires heavy JavaScript coding, HTMX lets you enhance HTML with attributes to bring dynamic behavior without sacrificing:

  • Accessibility
  • SEO
  • Developer familiarity

⚡ Core Features

  1. Declarative Attributes — hx-get, hx-post, hx-swap, etc.
  2. AJAX Requests — Asynchronous data fetching without complex JavaScript.
  3. Partial Page Updates — Update only what’s needed with hx-swap.
  4. WebSocket Integration — Real-time data updates.
  5. Server-Sent Events (SSE) — Push updates from server to client.

📝 Example: HTMX To-Do List

1<!DOCTYPE html>
2<html lang="en">
3<head>
4  <meta charset="UTF-8">
5  <meta name="viewport" content="width=device-width, initial-scale=1.0">
6  <title>HTMX To-Do List</title>
7  <script src="https://cdn.jsdelivr.net/npm/htmx.org@1.5.0/dist/htmx.min.js"></script>
8</head>
9<body>
10  <h1>HTMX To-Do List</h1>
11  <ul>
12    <li hx-post="/add" hx-swap="outerHTML">
13      <input type="text" placeholder="New task…">
14    </li>
15    <li hx-get="/tasks" hx-swap="outerHTML">
16      Loading tasks…
17    </li>
18  </ul>
19</body>
20</html>

🎯 Conclusion

This example highlights the simplicity and effectiveness of HTMX:

  • Use hx-post and hx-get to fetch and send data without page reloads.
  • Update only parts of the page with hx-swap.
  • Keep code clean while sticking to core web technologies.

HTMX is perfect for creating interactive, modern web experiences without unnecessary complexity.
